Question about Toshiba 53H71 53 in. Rear Projection Television

Open Question

53" Toshiba Rear Projection TV

I have the model t.v. above. The touch focus button says "Error" each time I press it. I don't know how to fix the convergence manually via the remote. The color isn't good....too much red, not enough green, but the color/tint isn't working very well. Also, there is now multiple images on the screen (ghosts) that just started. Any idea what the trouble is. Am wondering if this is going to be too costly to have a repairman come in to fix. The T.V. is only about 4 years old.

Also,check micro fuses F851,F852,etc.
and with a good digital meter, check resistors feeding B+ to
convergence circuit.
I have been using Stk392-110T made by Toshiba with no re-calls.Hitachi also has an upgrade IC.
And be sure to check your soldering of IC pins--good connect,
with no short.....T.

Replace Both of your STK ICs they are your convergence ics they are big black ICs will have Part# on them for example STK392-110, if they are 110s use 180s, if 020s use 040s other wise replace with exact same number. To get Parts call Electronix 1-800-223-3205

The chips are located on metal heat sinks with fins and are side by side. They are black(about 2 inches wide by 1 1/2 tall) and should have the STK-392-110 number printed on them in white.

Depending on your level of skill at this kind of work you may be able to do it yourself---if you need step by step instructions contact me---I have them in Microsoft word---start to finish repair including what you will need to do it.

If you are not able to do the repair yourself now is the slow time of year for TV repair shops----It should be fixable right in your home and the repair takes about an hour--I have done hundreds of these sets--some shops charge 300-400 but I do lots of them for 200-250 total cost. Make sure whoever you get changes BOTH of the chips!

Shop around and if they say "needs to go to shop" keep looking; any good tech can do this right in your home.

I do this here for free so if this helps you give me a vote here. If you need direct help contact me.

My color is washed out and dim and the colors are wrong . Toshiba 65h83 projection hd tv


I don't know your model, therefore I will tell you genericaly what the problem may be.

There are many things that can cause this type of fault. The response of the video amplifier stages would have to be checked right up through to the output that drives the projection. it is also possible that there is a fault with the colour demodulator. If the set uses projection tubes it is possible that the tubes are weak, or there is dirt in the optics. Colour demodulation problems can also cause the colours to not be correct. Many models using tubes have an optical transparent cooling fluid in front of the tubes. This fluid may have to be changed.

Touch focus error will not correct


If the touch focus isnt working and the picture has a 3D look you will need to change the conversion ICs. This is a straight forward repair just unsolder the old and solder in the new. You will need to replace both. They are located on a large aluminum heatsink and they will have STK numbers stamped on them they are quite large easy to find. The numbers will be something like STK392-110 or simallar. Let me know if you need anymore info.

Touch Focus Error


Even if the pix appears to be "OK", the internal convergence

alignment (in servicer mode) must be accurate within certain

parameters for the Touch Focus function to complete w/o error.

Adjustments should be done in "Full" mode,both HD & regular

signal.
